"Dave/CoolHeat is very knowledgeable about HVAC and consideration of importance to me. Also made me aware of new zoning requirements so that wasn't a blindside. On top of that, I got 3 quotes and Dave was the only one that followed-up with me. Crew showed up on time and worked efficiently to install the new unit. Works great."

"We hired Bertram to repair our central air. He arrived on time and did the repair. The repair should let us finish the season with the old season. We liked him, and have asked him to completely replace our system in the fall."

"It went very well. The problem was fixed completely. I'm very satisfied. I thought the problem was simply a defective pressure relief valve. Not the case - the problem was a water logged expansion tank. Joe drained the system, installed a new expansion tank, a new automatic water feed with back flow prevention, a new 30 psi pressure relief valve, and a new automatic air vent. All the replaced components were old, so it made good sense to me to replace them. Joe even installed shut-off valves on the water feed and expansion tank line so that if new the expansion tank ever becomes defective, it can be replaced without having to drain the system. When everything was installed, Joe refilled and purged the system and thoroughly tested it before leaving. I am completely satisfied with the worked performed. Excellent work and good value."

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
